rlhi's yinventionv relates to drum or 'pulley attachments forth'efwheel's' 'offvehicles f'to enable the use' of the vehicle as ahoisting yor powerv device 'orto' enable the vehiclelto fapply its ownpower,-"sothat-it maybe vdisengagedfrom a lmud-hole*- An rimportant`object "of the invention is to provide device lof'thi.'s characterwhich maybe readily applied-toa vehicle anda'e'- 'moved' therefrom# and.vhi'chV is capable of application Ito' vehicles,Y the wheels and hu-bsof fwhiichfare' of different fsizes. f

A further 4object-'fof the-invention isto provide-"a 'device Iof (this'character which may be readily and cheaply produced,`-which will bedurab'lfevand'efcientin service anda general improvement vvin'y'theiart.`

- Theseand'other vobjectsI attain by the construction'slrown in theaccompanying drawings,wherein forf-the `purpose of illustration'isvshown apreferred embodiment of my inventionfand wherein :-'-l

Figure 5 yisfan-illustration of thefcable for use withy thedrum. i

Referring now moreparticularly; to' tthe drawings," thel numeral 10designates-the spokes of a vehicle wheel and 11 the' outer plate of thepair usually employed for maintaining-theinnerends ofthe spokes inassembled relation. On automobile wheels, this outer plate is extendedoutwardly to provide the hub 12 of the wheel. The opening 15 of the drum14 receives the hub 12.

In accordance with my invention, I provide the inner faeepof the drum 14with a plurality, preferably three, of chordally directedy guides 16,the inner faces of which are slotted, as at 17, to permit passage of thestems 18 of the slides 19 operating within the guides. The ends of theguides 16 are preferably provided with stops preventing escape of theguides therefrom. The slide stems 18 are preferably circular in crosssection and provided with heads 20. Upon the stems are slidably mountedyokes 21, the outer ends of which are hinged at 22 to one arm ofU-shaped spoke clamps 23, the opposite {armfiof lwhich spoke'cla1np'-has pivoted thereto' y'a keeper/24,- the free end' of 1 Ewhichhas -anfope11ing1g25' for therpassage :ofna threaded stud 26 projectingfrom the'ayoke 212. At? :the'ffopposite` or'outerfside"off'the drum, I 1secure' a lplurality of "radially" directed tubes 27:, the outer end':ofweaoh of whichV is closed; l.as f at 28,y with ,the` exception of'an'axially disposed 'opening 29. Through this'opening 29' is directed `ashaft: BOiliaving suitable collars 31 which preventlongitu'dinalrmovement thereofi: Theiouter endof the shaft.r'ist-provided with..I a f thumbscrewf=32 whereby iti may y'be lrotated'and at .the inner en'dfthereof isthreadetll-for 'engagement 'in the!threaded=bore '33:of1l a-jaw carrier. 34. z

In ap,i plying the device to the vehicle fwheelythe drumv`gistsliipped"over the Vhulo'andi pushed toward thespokesrotthegfwlreelfas'efar .as possible'.s The `spoke clamps-are then-atcached-1 to :the spokes of. the'y wheel I:and f the keepers 24 thereofsecured in position. Itis .pointedioutf that ineapp-lyirrg?,A thef spokeclamps to'the spokes,- the sli'dablef-mounting f of vthese f spokeclam-ps willl ypermit'adj ustmentto compensate' for: any slightmisalign-v ment of the spoke, while` the. rotatable mounting .of theYclamp and the hinged connection-fs thereof perm-itthe cla-mp to-bereadily securedzabout the! spoke". I. The-yeke=21 bt'einzqaofr lesslengthitham--thestem 1S will permit adjustment of the clamps toward andaway,f1'fonwthey drum,-r so that proper engag-ementy with,` K thef spokemay beiV had.

Y their the`= spoke clamps are ally applied, the

jaws 35 are shifted into engagement with the hub 12 by rotating thethumbscrews r32 until the jaws are suiiiciently firmly engaged with thehub to insure against rotation of the drum.

It will be obvious that a device of this character maybe very readilyattached to the vehicle and is capable of application to wheels whichvary considerably in construction.

In the use of the drum 14, it may be employed either as a hoistingdevice or as a drive for machinery by. jacking up the wheel to which thedrum is applied. By securing to the drum one end of a cable, such asshown in Figure 5,'the opposite end ofrwhich is secured to Some fixedobject,

the drum may be employed for withdrawing a vehicle from a mudhole or thelike. The cable illustrated in Figure 5 is provided at one end with ahook 36 engageable in an opening 37 formed in one of the end Walls ofthe drum 14. The opposite end of this cablel has attached thereto hooks88 and 39 for engagement with a peg or post providing an anchor. It Willbe obvious that with the device attached in this manner, the cable willbe Wound upon the drum, moving the vehicle toward the peg or post andthus Withdrawn from a mudhole in which it has settled.

Since the construction hereinbefore set forth is obviously capable of acertain range of change and modification Without materially departingfrom the spirit of the in vention, l do not limit Vmyself to suchspeciiic structure except hereinafter claimed.

I claim z- 1 l. A drum for attachment to the hubs of spoked Wheelshaving an opening for the passage of the hub, circumferentiallyV spacedvslides shiftable chordally of the drum at the inner facel thereof,spoke engaging clamps carried by said slides and means at the outer faceof the drum and shiftable radiially thereof for clampingly engaging thehub of the Wheel.

2; A drinn for attachn'ient to the hubs of spoked Wheels having anopening for the passage of th-e hub, circumferentially spaced slidesshiftable chordallyV of the drum at the inner face thereof, spokeengaging clamps carried by and shiftable longitudinally upon said slidesand means at the outer face of the drum and shiftable radially thereoffor clampiugly engaging the hub of thel Wheel.

3. A drum for attachment to the hubs of spoked Wheels having'an openingfor the passage of the hub, circumferentially spaced slides shiftablechordally of the drum at the inner face thereof, spoke engaging clampscarried by and rotatably mounted upon. said slides and' means at theouter face of the drum and shiftable rad1- of spoked wheels having anopening forv the passage of the hub, circumferentially spaced slidesshiftable chordally of the drinn at the inner face thereof, spokeengaging clamps carried by said slides, means at the outer face of thedrum and shiftable radially thereof for clainpingly engaging the hub ofthe wheel, the clips being substantially U-shaped, there being a yokesurrounding the guide to which one arm of the clip is hinged and a catchhinged to the other arm of the guide and adapted for connection with theyoke.

6. A drum for attachment to the hubs of spoked wheels having an openingfor the passage of the hub, cireumferentially spaced slides shiitablcchordally of the drum at the inner face thereof, spoke engaging clampscarried by said slides, means at the outer face of the drum andshiftable radially thereof for clampingly engaging the hub ofthe Wheelincluding vtubes secured to the drinn .and extending radially' thereof,`a threaded member directed into the tube from the outer end thereof andheld against `longitudinal movement toward the outer end of the tube anda threaded tube in which the threaded member is engaged Ahaving at itsinner end ra jaw for engagement With the hub of the Wheel.
